13 eradicator 1.14 # has_multilib_profile:
14 eradicator 1.15 # Return true if the current profile is a multilib profile and lists more than
15     # one abi in ${MULTILIB_ABIS}. You might want to use this like
16     # 'use multilib || has_multilib_profile' until all profiles utilizing the
17     # 'multilib' use flag are removed from portage
18 eradicator 1.14
19     # is_final_abi:
20     # Return true if ${ABI} is the final abi to be installed (and thus we are
21     # on our last run through a src_* function.
22    
23     # number_abis:
24     # echo the number of ABIs we will be installing for
25    
26 eradicator 1.17 # get_install_abis:
27 eradicator 1.14 # Return a list of the ABIs we want to install for with
28     # the last one in the list being the default.
29    
30 eradicator 1.17 # get_all_abis:
31     # Return a list of the ABIs supported by this profile.
32     # the last one in the list being the default.
33    
34 eradicator 1.16 # get_all_libdirs:
35 eradicator 1.14 # Returns a list of all the libdirs used by this profile. This includes
36     # those that might not be touched by the current ebuild and always includes
37     # "lib".
38    
39     # get_libdir:
40     # Returns the libdir for the selected ABI. This is backwards compatible
41     # and simply calls get_abi_LIBDIR() on newer profiles. You should use this
42     # to determine where to install shared objects (ex: /usr/$(get_libdir))
43    
44     # get_abi_var <VAR> [<ABI>]:
45     # returns the value of ${<VAR>_<ABI>} which should be set in make.defaults
46     #
47     # get_abi_CFLAGS:
48     # get_abi_CDEFINE:
49     # get_abi_LIBDIR:
50     # Aliases for 'get_abi_var CFLAGS', etc.
51    
52     # get_ml_incdir [<include dir> [<ABI>]]
53     # include dir defaults to /usr/include
54     # ABI defaults to ${ABI} or ${DEFAULT_ABI}
55     #
56     # If a multilib include dir is associated with the passed include dir, then
57     # we return it, otherwise, we just echo back the include dir. This is
58     # neccessary when a built script greps header files rather than testing them
59     # via #include (like perl) to figure out features.
60    
61     # prep_ml_includes:
62     # Some includes (include/asm, glibc, etc) are ABI dependent. In this case,
63     # We can install them in different locations for each ABI and create a common
64     # header which includes the right one based on CDEFINE_${ABI}. If your
65     # package installs ABI-specific headers, just add 'prep_ml_includes' to the
66     # end of your src_install(). It takes a list of directories that include
67     # files are installed in (default is /usr/include if none are passed).
68     #
69     # Example:
70     # src_install() {
71     # ...
72     # prep_ml_includes /usr/qt/3/include
73     # }
74    
75     # create_ml_includes <include dir> <symbol 1>:<dir 1> [<symbol 2>:<dir 2> ...]
76     # If you need more control than prep_ml_includes can offer (like linux-headers
77     # for the asm-* dirs, then use create_ml_includes. The firs argument is the
78     # common dir. The remaining args are of the form <symbol>:<dir> where
79     # <symbol> is what is put in the #ifdef for choosing that dir.
80     #
81     # Ideas for this code came from debian's sparc-linux headers package.
82     #
83     # Example:
84     # create_ml_includes /usr/include/asm __sparc__:/usr/include/asm-sparc __sparc64__:/usr/include/asm-sparc64
85     # create_ml_includes /usr/include/asm __i386__:/usr/include/asm-i386 __x86_64__:/usr/include/asm-x86_64
86    
87 kito 1.31 # get_libname [version]
88     # returns libname with proper suffix {.so,.dylib} and optionally supplied version
89     # for ELF/MACH-O shared objects
90     #
91     # Example:
92     # get_libname libfoo ${PV}
93     # Returns: libfoo.so.${PV} (ELF) || libfoo.${PV}.dylib (MACH)
